LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 315,100, dated April 7, 1885.

(No model.)

of the auxiliary chamber b. Through thelower represented in the accompanying drawings, of

which*n Figure l is a top view, Fig. 2 a side elevation, and Fig. 3 a longitudinal section, of a shuttle provided with my invention, the nature of which is defined in the claims hereinafter presented. Fig. @L is a perspective View of the thread or yarn guide. Fig. 5 is a transverse section of the shuttle, taken online I l of Fig. l, or through the stopping-ear of the yarnguide; and Fig. 6 is a side view of the slotted friction-screw to be described.

The invention is to enable a weaver to expeditiously thread a shuttle or pass the yarn of the cop through the side of the shuttle without having to accomplish this by the aid of suction of his mouth applied to the shuttle, and thereby drawing filaments therein to his detriment.

In such drawings, A denotes the shuttlebody, having in it a cop-chamber, a, and in advance thereof an auxiliary chamber, b, the latter being forfreception of the threadingguide C, by which the yarn from the cop c on the spindle B is guided into a hole leading laterally out of one side of the shuttle. Between the two chambers, or in the partition d separating them, is a guide-groove, e,within which is the slotted friction-screw D. This screw, slotted from its smaller end diametrically across it and lengthwise in the shank, is screwed upward into the said partition with the slot in the guide-groove e, allbeing as represented. On turning the screw so as to bring its slot more or less oblique to the groove, friction will be produced on the yarn while being drawn from the'cop through the groove, such friction being to prevent the yarn from being delivered too fast while the shuttle may bein Hight across the race-beam of a loom.

The threadingguide C is bent or hooked at its rear part, as shown at f, and from thenceto its longer part it is a wide plate-spring, g, formed as shown. It rests at its free end onabearing or shoulder, h, at the upper part and frontend portion of the spring g, and directly over a hole, i, in the hook f below it, is a hole, k, toadmit of a fastening-screw, Z, being inserted in such hole z and screwed into the body of the shuttle, in order for such screw to secure the threading-guide in place. The hooked part of the threadingguide extends and opens into an educt or hole, m, leading out of the auxiliary chamber and laterally through the shuttlebody. Beneath the spring g there is in the shuttle-body a hole, n, for a weavers finger to pass to the spring in order to force it upward off the bearing or shoulder 7L, to enable him t0 pass the yarn under and about the spring and into its hook. After having done this he can easily seize the yarn in the hook and draw it through the hole m.

To prevent the spring g from being overstrained by the linger of an operative, such spring has an ear, o, projecting from it into a recess, p, in the shuttle-body. On pressing upward the spring sufliciently the ear wllbring up against the top of the recess, and by such the spring will be stopped from advancing higher.

In threading the shuttle the weaver has not to suck the yarn through the lateralopening of the shuttle-body, but with the forefinger of his hand holding the shuttle he is to force upward the spring g of the threading-guide C, and next is to draw the yarn around under the spring and into the hook, after which he is to seize the yarn and pull it laterally out of the hook and through the hole m.

It will be seen that with the aforesaid threading-guide I do not use any slit for the passage of the yarn from the shuttle in the side of its chamber and leading down from the top thereof into the eye or opening in the side of the shuttle-body.

I claim# I, The combination, with a loom shuttle body provided with the thread educt or eye, of the yarn threading guide arranged in such body and fixed thereto by a screw, substantially as described, such guide consisting of a spring hooked at its rear part and provided in the hooked part with two holes, one larger in diameter and arranged directly over the other, as set forth.

2. The yarn-threading guide consisting of a Consisting of the spring hooked at its rear end T and arranged,as described, in the shuttle-body, and provided with an ear extending laterally from it, the said guide,with the shuttle-body, -provided. with the delivery-eye and chambered to receive and hold sueh guide, and furnished with the shoulder or bearing for the free end ofthe guide to rest upon, the stopping-recess for the ear to enter, and the finger-receiving 2o hole underneath the guide, all being substantially as represented.

5. The combination Of the threading-guide, consisting of the hooked spring, as described, With the shuttle-bodyhaviug a chamber for 25 reception of such guide, and-a thread-passage leading out of the said chamber, a shoulder or bearing for the guide in theupper part of such Chamber, and a hole through the bottoni of the chamber foraeeess by the Weavers finger 3o to the guide for moving it off the shoulder or bearing, all being substantially as set forth.
